While speaking in Bangkok, President Obama Sunday said he was in touch with players across the region in hopes of halting the fighting. While defending Israel's right to defend itself against the rocket fire, he also warned of the risks the Jewish state would take if it were to expand its air assault into a ground war.

"If we see a further escalation of the situation in Gaza, the likelihood of us getting back on any kind of peace track that leads to a two-state solution is going to be pushed off way into the future," Obama said.
